Coupled simulation of CFD and human thermoregulation model in outdoor wind environment

Understanding of dynamic and transient wind environment is crucial to evaluating the outdoor thermal comfort pedestrians. The thermophysiological responses human body depend on both interaction with climate internal thermoregulation. coupled simulation CFD thermoregulation model provides a pathway predict under non-uniform conditions where local effects may dominate comfort. In this work, we explore potential environmental conditions. JOS-3, which consists 85 nodes 17 segments, used simulate physiological obtained mean skin temperature fed into as boundary condition manikin. interactions between surrounding in tunnel, represented by convective radiant heat transfer coefficient, are calculated serve inputs for JOS-3 model. results exhibit that velocity 1 m/s turbulent intensity 11.6%, coupling can converge within two iterations. This because coefficient not significantly affected assigned airflow velocity, higher than value an indoor environment. study demonstrates workflow could be useful tool different future.
